Commit 0244756e ("ufs: sb mutex merge + mutex_destroy") introduces deadlocks in ufs_new_inode() and ufs_free_inode(). Most callers of that functions acqure the mutex by themselves and ufs_{new,free}_inode() do that via lock_ufs(), i.e we have an unavoidable double lock. The patch proposes to resolve the issue by making sure that ufs_{new,free}_inode() are not called with the mutex held. Found by Linux Driver Verification project (linuxtesting.org).

Pull xfs fixes from Dave Chinner: "The fixes all address recently discovered data corruption issues. The original Direct IO issue was discovered by Chris Mason @ Facebook on a production workload which mixed buffered reads with direct reads and writes IO to the same file. The fix for that exposed other issues with page invalidation (exposed by millions of fsx operations) failing due to dirty buffers beyond EOF. Finally, the collapse_range code could also cause problems due to racing writeback changing the extent map while it was being shifted around. The commits for that problem are simple mitigation fixes that prevent the problem from occuring.

The update_walltime() code works on the shadow timekeeper to make the seqcount protected region as short as possible. But that update to the shadow timekeeper does not update all timekeeper fields because it's sufficient to do that once before it becomes life. One of these fields is tkr.base_mono. That stays stale in the shadow timekeeper unless an operation happens which copies the real timekeeper to the shadow. The update function is called after the update calls to vsyscall and pvclock. While not correct, it did not cause any problems because none of the invoked update functions used base_mono. commit cbcf2dd3 (x86: kvm: Make kvm_get_time_and_clockread() nanoseconds based) changed that in the kvm pvclock update function, so the stale mono_base value got used and caused kvm-clock to malfunction. Put the update where it belongs and fix the issue.

That change relied on the per-cpu charge caches to mostly swallow the res_counter costs, but it's apparent that the caches don't scale yet.
